Detection of MBL-2 gene expression in intestinal biopsies of celiac patients by in situ reverse transcription polymerase chain reaction
AbstractCeliac disease (CD) is an autoimmune enteropathy triggered by ingestion of gluten in genetically susceptible subjects and represents one of the most frequently occurring, treatable, lifelong autoimmune disorders. Undetected or untreated CD may cause late more severe complications (Farrell and Kelly, 2002). So far, several factors have been identified as possible agents responsible for CD. There is a strong evidence that CD is associated with specific HLA haplotypes (HLADQA1* 0501, DQB1*0201 or DQA1*0301, DQB0302) (Sollid and Thorsby, 1993). Recently it has been demonstrated on Italian patients that polymorphisms of the first exon of MBL2 gene, which encodes for Mannose Binding Protein (MBP), could play a pathophysiological role in celiac disease (Boniotto et al., 2002). MBP is a serum protein involved in the natural or innate immune response. MBP acts as an ante-antibody and can enhance opsonisation, or can activate the classical pathway of the complement on bacteria, viruses and fungi (Sastry and Ezekowitz, 1993).
PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
